PZZ700 113 Pm Pdt Sun May 5 2024
Synopsis for the far southern california coast - At 1 pm, a 991 mb low was over central utah and the attendant cold front was just south and east of southern california. Meanwhile, a 1029 mb high was about 1,400 miles west of point conception. Strong and gusty west to northwest winds through this evening will generate hazardous boating conditions, especially in the outer waters. Weaker onshore flow with a coastal eddy follows for Monday through Wednesday.

Area Forecast Discussion National Weather Service San Diego CA 917 PM PDT Sun May 5 2024

SYNOPSIS
Chilly overnight temperatures tonight into Monday morning, with lows 5 to 10 degrees, locally up to 15 degrees in the deserts, below normal. Gradually warming conditions expected through mid-week.
Periods of breezy westerly winds expected in the afternoons and evenings in the mountains and deserts early this week, with the potential for offshore winds Wednesday. Warmer and dry conditions are expected into next weekend.

DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...

Satellite imagery at 9 PM is showing mostly clear skies, with some clouds against the coastal slopes of the mountains. Winds have died down, with only a few gusts 35-40 mph below the San Gorgonio Pass and in the High Desert. Winds will continue to weaken through midnight into early Monday. A peak wind gust summary and rainfall totals have been headlined on our weather.gov/sandiego homepage.

Chilly conditions expected overnight by May's standards. Lows Monday morning could be up to 15 degrees below average for this time of year in the deserts. There is a 20% chance lows in portions of the High Desert will fall to the mid-30s. Winds are expected to weaken but not completely diminish in the High Desert which will be a limiting factor in how cold it gets there overnight. Daytime temperatures will rebound under mostly sunny skies Monday. Highs temperatures are expected to be 3 to 10 degrees warmer than Sunday for the coast and valleys; 15 to 20 degrees warmer than Sunday in the mountains and High Desert; and 4 to 12 degrees warmer than Sunday in the lower deserts. That translates to highs in the mid to upper 60s along the coast, low to mid-70s for the valleys and High Desert, mid-80s for the low desert, and mid-50s to 60s for the mountains.

From the previous discussion issued at 2 PM May 5...

Southern California will remain under weak cyclonic flow through at least Wednesday as a ridge builds near the Pacific Northwest and a strong upper low is centered over the central US. Warmer temperatures are expected on Monday, with more gradual warming occurring on Tuesday and Wednesday. Breezy onshore west to northwest winds will develop each afternoon and evening over the mountains and deserts, with peak gusts approaching 40 mph.

For the second half of the week, ensemble guidance is pointing towards a positively-tilted shortwave breaking off from the parent low over the central US, and retrograding towards the Desert Southwest. A period of offshore winds are expected on Wednesday as this low strengthens, but will turn predominantly back onshore for Thursday and Friday as the low becomes centered near the Four Corners region. Otherwise, little day-to-day change is expected temperature wise Wednesday through Friday, with highs remaining within a few degrees of seasonal averages. Marine layer low clouds will continue for the coastal areas and portions of the valleys each night and morning, potentially deepening and spreading further inland by next weekend.
